Kirkland Lake Discoveries advances KL West multi-target pipeline

District-wide 65-hole drill program identifies multiple VMS-style, intrusion-related gold and structurally controlled gold systems along 17-km Winnie Lake Stock corridor

Toronto, Ontario--(Newsfile Corp. - August 18, 2026) - Kirkland Lake Discoveries Corp. (TSXV: KLDC) (OTCQB: KLKLF) ("KLDC" or the "Company") announces receipt of the complete gold and multi-element analytical dataset from the KL West diamond drilling campaign completed on April 1, 2026. The program comprised 65 drill holes totalling 19,161.9 m and 9,616 original drill-core samples.

Integration of the analytical data with geological logging, alteration, mineralization, structural interpretation and regional geophysics has identified multiple fertile hydrothermal systems and established a district-scale framework for vectoring toward higher-priority discovery opportunities.

Highlights

Completed 65-hole, 19,161.9-metre district-scale drill campaign across 10 target areas

Identified three distinct mineralizing systems across KL West, with multiple independent discovery opportunities

Gold mineralization confirmed across multiple target areas , including:

5.57 g/t Au over 1.13 m (Winnie Lake)

1.41 g/t Au over 3.40 m (Wolverine Bend)

1.87 g/t Au over 0.80 m (Wolverine Bend)

38 holes intersected signatures associated with intrusion-related gold systems

27 holes intersected polymetallic signatures associated with VMS-style systems

Multiple priority drill corridors now identified for follow-up exploration

The importance of this program extends well beyond any single drill intersection," said Stefan Sklepowicz, Chief Executive Officer of KLDC. "Our regional targets repeatedly intersected the same fertile hydrothermal signatures along kilometre-scale corridors, giving us a much clearer understanding of the mineralizing system across the property. We can now see where the system is distal, where it becomes more
